Discussion Overview

The discussion centers on the duration required to obtain a PhD, specifically for individuals with a Bachelor of Science (B.Sc.) degree and no master's degree. Participants explore average times, shortest possible durations, and variations based on geographic location and academic structure, particularly in the fields of physics in different countries.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants suggest that the average duration for a PhD in physics is around 4 years, particularly for students without prior master's level coursework.
  • Others argue that in the US, the average time is often a minimum of 5 years for a combined master's/PhD program, with many students taking 6 to 8 years to complete their degrees.
  • A participant notes that the median time for completing a PhD in physics in the US is about 5 years, but it can vary from 4 to 8 years.
  • One participant questions the shorter duration of PhDs in the UK, comparing it to the longer educational pathway in Poland, which includes a 3-year bachelor's, a 2-year master's, and a 4-5 year PhD.
  • Another participant explains that UK PhD programs typically aim for a 3-year completion time due to funding structures, although many students exceed this timeframe by 6 months to a year, and that UK students begin research immediately with minimal coursework.

Areas of Agreement / Disagreement

Participants express varying views on the average duration of PhD programs, with no consensus on a single timeframe. There are competing perspectives on the differences in PhD structures between the UK and the US, as well as the implications of educational backgrounds from different countries.

Contextual Notes

Participants highlight that the duration of a PhD can be unpredictable and is influenced by various factors, including the specific institution, funding arrangements, and individual progress. There are also differences in educational systems that affect the overall timeline.

As stated in the title, how long does it take to obtain a PhD for someone with an B.Sc. undergraduate degree, but without a master's degree? I would like to know the average time, as well as the shortest time possible. Thanks!
 
Physics news on Phys.org
This varies quite a lot with the place where you plan to get your PhD and the subject. Which country are you in, and what field are you asking about?
 
Oops, apologies, I forgot to include that info... :rolleyes:

I am referring to a PhD in Physics. I am currently residing in Singapore but I am intending to pursue my post-grad studies in either US or UK.
 
I think the average is probably somewhere in the region of 4 years, especially for a student entering with no masters level classes under their belt.

In the UK.
In the US, it's often a minimum of 5 years for a combined ms/phd and it usually ends up in the 6-8 year range. http://www.nature.com/nature/journal/v431/n7006/full/nj7006-382a.html->it's from 2004, but the numbers haven't changed much.

Just a word of advice, that information is going to be totally useless to you. Your Ph.D. is done when it's done, and there is no way of predicting how long that is.

Median time in the US for physics is about five years, but it can go anywhere from four to eight.
 
How is this possible, that it's so fast in UK?

In Poland we have 3 years Bachelor's degree, 2 years Master's degree, and then PhD that takes about 4-5 years, which gives 10 years.
 
In the UK the length of funding is set at 3 years, so this is the aim though more students are finding that they overrun - generally from 6 months to a year.

One of the reasons for the short time is that the set-up is different in the UK than it is in the USA: UK PhD students have to take a minimal amount of credits, and so start their research immediately. Also, undergraduate degrees contibute to this a little: in the UK, degrees will be 4 or 5 years and the student will only take one or two subjects throughout: a physics degree will only need classes in physics and maths, and generally it is not an option to choose classes outside of this.
